Stones pelted at Kollam MP's house in Kerala

He said the posters on his house walls were threatening in nature, saying Premachandran is a deserter and a renegade, as he is now the disciple of Congress president Sonia Gandhi and Chief Minister Oommen Chandy.

The police have begun a probe into the matter.

Premachandran, a senior member of the Revolutionary Socialist Party (RSP), was an ally of the CPI-M led Left Democratic Front for the past three decades.

Ahead of the recent Lok Sabha polls, the RSP which was hoping to field its candidate from the Kollam Lok Sabha seat was peeved when the CPI-M announced the candidature of party politburo member and sitting legislator M.A. Baby.

Consequently, the RSP announced they were moving out of the LDF and would join the Congress led United Democratic Front.
